繁昌窑青白瓷化学组成分析及其衰落原因考察

Study on the Chemical Composition Analysis of Blue-White Porcelain from Fanchang Kiln and Reasons for Its Fall

1．引言 繁昌窑遗址位于安徽省芜湖市繁昌县境内，其窑址散布在县城南郊和西郊的柯家冲、骆冲等多个地点，是我国长江下游地区一处专烧青白瓷的窑址。根据历年的考古调查与发掘资料来看，该窑创烧于五代，北宋早期是其鼎盛期，北宋中期后渐趋衰落。

The Fanchang kiln was the first Chinese kiln to produce blue-white porcelain as early as the Five Dynasties period. The chemical composition of blue-white porcelain from the Fanchang kiln was analyzed by wave disperse X-ray fluorescence spectrometry. The analytical results show that the chonical composition of porcelain body in the middle Northern Song dynasty changed obviously. The elements of Silicon dioxide （SiO2）, major fluxes such as Potassium oxide （K2O） and Sodium oxide （Na2O） and color-causing elements like ferrous iron （Fe2） and Titanium （Ti） increased while Aluminum oxide （Al2O3） decreased down. To combine with the analysis of minor elements, this paper suggests that such changes should be attributed to the quality decline of raw materials during the Middle Northern Song Dynasty. This might have led to the rapid fall of this industry.
